A Technical Comparison of 802.11n to 802.11g

A Technical Comparison of 802.11n to 802.11g Abstract 802.11n was developed to address issues of distance and speed. These were issues with wireless g and especially big issues with legacy devices that were used previously. Wireless N devices allow for a wider range by using multiple-input multiple-out and multiplexing allowing more data to be sent at a given time than before in previous a/g devices. It also allows for better communication between the radios and receivers to modify the signal so that noise becomes less of an issue and getting the best signal to the receiver is more of the issue. This 802.11n development led to a faster more evolved internet solution and will lead us to even faster solutions and even great distances spanned due to the distances already accomplished by this top of line, high-speed solution. It accomplishes all of this while still maintaining a high-level of security and not compromises on speed or power consumption.

A Technical Comparison of 802.11n to 802.11g

In less than a decade, wireless LANs have evolved from an interesting idea to an indispensable technology for millions of businesses and consumers. So it is just a matter of what technology to use. Currently there are two heavily used technologies which are wireless g and wireless n. This will be explained in full detail below as we look at the breakdown between both of these. Wireless g was created to increase a powerful tool for increasing the mobility and productivity of users, and have unlocked a new generation of wireless-enabled applications. Its characteristics are depicted in the table below. Frequency Spread Spectrum Technology 2.4GHz ISM band ERP; ERP-OFDM , ERP-DSSS/CCK are mandatory ERP-DSSS/CCK:1,2,5.5 and 11Mbps Data Rates ERP-OFDM:6,12,24Mbps Also supported: 9,18,36,48 and 54Mbps Backwards Compatibility Date Ratified 802.11 HR-DSSS and DSSS 2003 802.11g Characteristics Wireless G is still used today but is...
